Well, here are the characters that I have designed and colored for my crossover so far.
Will be updated with more characters as they come.
From Left to Right:
Otto Osworth (Time Squad)
Grim (Grim Adventures of Billy and Mandy)
Danny Phantom/Fenton (Danny Phantom)
Bubbles, Blossom, Buttercup (Powerpuff Girls)
Dee Dee and Dexter (Dexter's Lab)
Mandy and Billy (Grim Adventures of Billy and Mandy)
Cosmo, Timmy Turner, Wanda (The Fairly Oddparents)
Doug Funnie (DOUG)
Kim Possible (Kim Possible)
Johnny Bravo (Johnny Bravo)
Penelope Pitstop (Wacky Races)
I don't like the background too much because I tried mixing the logos of Cartoon Network, Nickelodeon, and Disney, but it doesn't look right.I'm sure it will be updated along with characters later on.
